Carl,
We have W32 #251 and while we haven't had her out in any big storms we've been through some really snotty chop and she doesn't make much noise at all. The only real noise we get out of her is when I step on the cabin sole and put all my weight there. I'm a heavy guy.
1st, is your boat a kit or a factory finished boat?
2nd. Have you checked the tabbing of the main bulk head to the hull. When I discussed our boat with a PO that circumnavigated 3 times in it, he cautioned me to double check this part of the boat. He had spent a lot of time having it glassed over again to make sure it was secure.
Do you notice any localization of the sound or is it all over? What are you doing when it is creaking so much?
